Terry even recalls that the Manchester United boss had such an effect on him he even made notes, despite none of his team-mates doing so.

"From the moment Jose came in, I knew I wanted to be a coach," said pens Terry. "Before then, as a player, I just went out on the pitch and played.

"Didn’t think about the training sessions, the coaching, the size of the pitches we’d train on, anything. Then I saw something special, and it was all about preparation."

Terry then goes into detail, adding: "He’d be out there at 8am, putting out cones, making sure there were enough bibs, enough balls.

"He brought ballboys into the training ground to make sure we would get balls back on the pitch as soon as possible. As a group of players, not just me, we all took note of how good he was right from the start.
